James van der Beek and his wife Kimberly Brook just announced she is expecting baby number two, and she’s already got quite the bump!

At the Great Giggle Giveback benefiting Baby Buggy, Kimberly debuted her adorable baby bump. The couple, who have been married for a little over a year, already have a daughter Olivia, who was born last September.

The Dawson’s Creek actor chatted about the Baby Buggy organization, and why they feel it’s important to give back.

“After having our first child, we saw firsthand how many things a baby quickly outgrows. And now that we’re on to our second, Baby Buggy is an organization we love to support as they very efficiently put items into hands that need them most.”

Baby Buggy is a nonprofit organization founded by Jerry Seinfeld‘s wife Jessica in 2001, and provides essential gear, clothing, and educational services to families in need.

They were also joined by Tiffani Thiessen at the store’s launch in Santa Monica. Check out the photos in the gallery!
